I had also some trouble getting volume backed instances to boot. I use
xen hypervisor and found out that the instance was assigned a device
name of "vda" (which is set by default) instead of xvda, I filed a bug
report for this. Have you nova-compute.logs? I can't find them in your
link. They should give a hint about the device name or other possible
causes. Since the volume is created but immediately destroyed, I guess
nova has a problem with the block device.

I'm trying my newly installed Openstack system and I'm getting
problem in starting my first instance.

The web GUI say (this might be from another test, but I always
get the same):

I can see nothing relevant in this that would make it fail!
The only thing that bought my eye was that it isn't removing
the iSCSI target, because there isn't one..
This is (most of) my cinder.conf file:
----- s n i p -----
[DEFAULT]
my_ip = 10.0.4.1
storage_availability_zone = nova
default_availability_zone = nova
enabled_backends = lvm
iscsi_target_prefix = iqn.2010-10.org.openstack:
iscsi_ip_address = $my_ip
iscsi_port = 3260
iscsi_iotype = blockio
iscsi_write_cache = on
volume_group = blade_center
scheduler_driver = cinder.scheduler.filter_scheduler.FilterScheduler
[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = blade_center
iscsi_protocol = iscsi
iscsi_helper = tgtadm
----- s n i p -----
PS. Creating the instance from an already existing, empty
volume, didn't work either. Same message, and even less
information in the log.
